Audio grade transformers for use with our HPULN power supplies, in amplifiers and other high-class audio devices.
For a nice look the transformer has an internal threaded sleeve of M6 size and a closed top.Unlike commercial power line transformers, the AUDIO GRADE version is covered with a black Mylar tape which gives it an aesthetic appearance. The epoxy filled center with an opening for the M6 screw eliminates a need for an additional mounting bracket. The neoprene gum pad affixed to the bottom successfully eliminates transmission of vibrations.The entire construction utilizes high-class, laboratory-tested parts. The core and the windings are impregnated, and the production process is being scrupulously controlled at every step.
